## Kubernetes By Component - Part 5

### Upgrading from 1.9 to 1.11 - ServiceAccounts

As I prepared to present the four previous posts (part 1, part 2, part 3, part 4) as “Dissecting Kubernetes” at KCDC X, I tried to upgrade from v1.9 to v1.11 of Kubernetes and I found that when we only have the kubelet and the kube-apiserver we run into a permissions issue we didn’t have before.
